you guys are all missing the point.
The government is trying to regulate and profit off of the players in order to increase government income + diplomatic power. While this isn't unreasonable on the surface, in actuality the players are the only thing standing in the way of the apocalypse destroying the real world. Only players can fight against monsters with their abilities and boosted stats. Therefore, the government should instead be investing in players in order to make them stronger and level up, in order to combat the eventual stronger monsters.
Only MC survived to the end of the game - and even he couldn't beat the "real" final boss. Doesn't that mean the human race will be completely wiped out before the final battle unless he can assemble a team of max level players?
However most players and leaders are too caught up in their own personal greed to realise this - plus only the MC knows what the final battle and last ten years of gameplay was like. It's not about him being the strongest, it's about him having the most knowledge.
